About PrivateMark

PrivateMark does two things, on-device, no servers, no accounts. 1) Trace any leak. Before you share a photo, PDF, Word or PowerPoint, it weaves in an invisible, per-recipient watermark. If a copy leaks, feed it back and it names whose copy it was. 2) Hidden Photo. Send a picture everyone sees as an innocent cover; your trusted contact opens it in PrivateMark to reveal the real photo, sealed with AES-256.

About Clarity

Clarity is a high-fidelity, browser-based screen-sharing tool specifically built for sharing detail-heavy content like code, documents, and design work—materials that standard chat applications often blur or compress. It is an ideal solution for developers, designers, and remote teams who need to present sharp, readable visuals without quality loss.

With Clarity, getting started is friction-free: there is no installation and no account creation required. Users can create an expiring room instantly, share a single link, and present their screen to up to 10 viewers. The tool allows hosts to select between text- or motion-optimized modes, approve viewers manually for extra security, and monitor every live connection. To ensure fast performance, streams are routed peer-to-peer whenever possible.

  • No software installation or account sign-up required
  • Supports text- or motion-optimized stream modes
  • Secure expiring rooms with live connection monitoring and viewer approval
  • Peer-to-peer streaming when possible for efficient performance
